How sad! The young Twilight lovers won’t see each other for MONTHS because of their work schedules!

The 20-year-old Twilight starlet looked down in the dumps at LAX July 11 as she set off to join her On the Road co-stars Kirstin Dunst, Garrett Hedlund and Sam Reilly for her month-long “beatnik bootcamp.” The film, which is based on Jack Kerouac’s iconic Beat Generation novel, starts shooting August 2 in Montreal, Canada for more than a month before moving to New Orleans for a month and Mexico for a few weeks before wrapping back in Montreal. This means that K-Stew potentially won’t see her man until NOVEMBER, when they start shooting Breaking Dawn, the fourth Twilight Saga installment.
